Format:: Supplied as a liquid in 10mM PBS. No preservative added. BSA-Free. Labeled with Fluorescein isothiocyanate (FITC).
Extra Details:: Beta-catenin associates with the cytoplasmic portion of E-cadherin, which is necessary for the function of E-cadherin as an adhesion molecule. In normal tissues, beta-catenin is localized to the membrane of epithelial cells, consistent with its role in the cell adhesion complex. In breast ductal neoplasia, beta-catenin is usually localized in cellular membranes. However, in lobular neoplasia, a marked redistribution of beta-catenin throughout the cytoplasm results in a diffuse cytoplasmic pattern. Immuno-staining of beta-catenin and E-cadherin is helps in the accurate identification of ductal and lobular neoplasms, including a distinction between low-grade ductal carcinoma in situ (DCIS) and lobular carcinoma. Additionally, some rectal and gastric adenocarcinomas demonstrate diffuse cytoplasmic beta-catenin staining and a lack of membranous staining, mimicking the staining pattern observed with lobular breast carcinomas. Applications: Suitable for use in Western Blot, Flow Cytometry, Immunofluorescence, Immunoprecipitation and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 0.5-1ug/ml Immunohistochemistry (Formalin fixed paraffin embedded): 1-2ug/ml/30min @ RT Flow Cytometry: 0.5-1ug/10e6 cells Immunofluorescence: 1-2ug/ml Immunoprecipitation: 1-2ug/500ug protein lysate Optimal dilutions to be determined by the researcher. Positive Control: HeLa or MCF-7 cells. Breast carcinoma Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: FITC conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
